Mobile frame receiving material from hopper is formed by container (4) with a thin partition (18) separating it into two chambers (6,8). Hopper conduit outlet (12) is arranged at a distance (d) above the partition with (d) being not less than the longitudinal distance (l) separating the hopper edge (2) from the partition multiplied by gradient of the slope of the product.
